Abstract:
The use of nanotechnology in terms of nanoparticles, carbon nanotubes, and quantum dots, when exposed to the plants, helps increase their productivity. It is worth the effort to comprehend the fate of these nanoparticles in plants. Bonechar derived from bones is a rich source of C, P, Ca2+, and Mg2+ nutrients, which can significantly contribute to the growth of the plants. This study focused on the uptake of nano-bonechar (NBC) in the Syngonium podophyllum plant, and its effects on plant growth under hydroponics and soil systems. The compound microscopy and SEM-EDX results confirmed the presence of NBC in the leaves and roots of the plants in hydroponics and soil systems. The FTIR spectra reflected the presence of functional groups of the NBC in the leaves of the Syngonium podophyllum plant. The plant\'s growth parameters showed an increase in fresh weight, dry weight, shoot length, chlorophyll content, leaf count, total Ca2+, total PO43-, and total organic carbon of plants in both systems. The NBC not just improved plant physiochemical parameters but also built up the soil quality in terms of bioavailable Ca2+, PO43-, water holding capacity, and soil organic matter. It is concluded that the production of carbon-based NBC not only helps manage bone waste but also their efficient uptake in plants significantly improving plant productivity.
摘要:
纳米技术在纳米粒子方面的应用,碳纳米管,和量子点,当暴露在植物中时,有助于提高生产力。理解这些纳米粒子在植物中的命运是值得的。来自骨骼的Bonechar是C的丰富来源,P,Ca2+,和Mg2+营养素,这可以显著促进植物的生长。这项研究的重点是纳米骨灰(NBC)在深叶植物中的吸收,及其对水培和土壤系统下植物生长的影响。复合显微镜和SEM-EDX结果证实了水培和土壤系统中植物的叶片和根中存在NBC。FTIR光谱反映了深叶植物叶片中NBC官能团的存在。植物的生长参数显示鲜重增加,干重,射击长度,叶绿素含量,叶数,总Ca2+,总PO43-,以及两个系统中植物的总有机碳。NBC不仅改善了植物的理化参数,而且还在生物可利用的Ca2+方面建立了土壤质量,PO43-,持水量和土壤有机质。结论是,基于碳的NBC的生产不仅有助于管理骨骼废物,而且还有助于它们在植物中的有效吸收,从而显着提高了植物的生产力。
